docker-postgis
|
||||
==============
|
||||
# docker-postgis
|
||||
|
||||
Dockerfile for postgis
|
||||
A simple docker container that runs PostGIS
|
||||
|
||||
|
||||
## Build
|
||||
|
||||
To build the image do:
|
||||
|
||||
```
|
||||
docker build -t kartoza/postgis git://github.com/timlinux/docker-postgis
|
||||
```
|
||||
|
||||
Run
|
||||
---
|
||||
|
||||
To create a running container do:
|
||||
|
||||
```
|
||||
sudo docker run --name "postgis" -p 2222:22 -p 25432:5432 -d -t kartoza/postgis:2.1
|
||||
```
|
||||
|
||||
## Connect via psql
|
||||
|
||||
To log in to your container do:
|
||||
|
||||
Connect with psql (make sure you first install postgresql client tools on your
|
||||
host / client):
|
||||
|
||||
|
||||
```
|
||||
psql -h localhost -U docker -p 25432 -l
|
||||
```
|
||||
|
||||
You can then go on to use any normal postgresql commands against the container.
|
||||
|
||||
Under ubuntu 14.04 the postgresql client can be installed like this:
|
||||
|
||||
```
|
||||
sudo apt-get install postgresql-client-9.3
|
||||
```
|
||||
|
||||
|
||||
# Storing data on the host rather than the container.
|
||||
|
||||
|
||||
Docker volumes can be used to persist your data.
|
||||
|
||||
```
|
||||
mkdir -p ~/postgres_data
|
||||
docker run -d -v $HOME/postgres_data:/var/lib/postgresql kartoza/postgis`
|
||||
```
|
||||
|
||||
You need to ensure the ``postgres_data`` directory has sufficinet permissions
|
||||
for the docker process to read / write it.
|
||||
|
||||
|
||||
|
||||
Connect via ssh
|
||||
---------------
|
||||
|
||||
To log into your container do:
|
||||
|
||||
```
|
||||
ssh root@localhost -p 2222
|
||||
```
|
||||
|
||||
Default ssh password is 'postgis'
|
||||

||||
